what is different form, follow as:
(1)code XBYTE *AA[]={...}; (2)code void (*BB[])(void)={...};
i trace some codes, and the coding above is not realizing.
"the coding above is not realizing." Sorry, what do you mean by that? Do you mean that it doesn't compile? If so, there's probably a fault in your definition of XBYTE. If you're using the standard Keil definition of XBYTE, then it will never compile - read the description of XBYTE in the C51 Manual.
